Abstract (en)
A process for making a heather-dyeable or precolored heather yarn product comprises supplying a first crimped continuous filament yarn in the form of a loose matrix substantially free of filament entanglement and a second crimped continuous filament yarn which is differentially dyeable or precolored with respect to the first yarn. The second yarn is fed through a first entangling or interlacing zone and exposure of the second yarn to a fluid jet in the first entangling zone is randomly controlled to produce a color-point yarn product as the second yarn exits the first entangling zone, in which the color-point yarn product has relatively compact nodal regions of high entanglement of the filaments of the second yarn separated by bulkier regions of the same filaments relatively free of entanglement. The first yarn and the color-point yarn product are then fed through a second entangling zone which randomly entangles filaments of the yarns from yarn to yarn and in which yarn-to-yarn filament commingling is substantially prevented within the nodal regions of the color-point yarn. An apparatus for performing the process includes a randomly controllable fluid valve supplying fluid to the fluid jet in one embodiment, and a randomly controllable yarn guide to move the yarn into and out of the fluid jet in another embodiment. <IMAGE>
